Bac2 announces all-moulded bipolar plates for high temperature PEM fuel cells

Southampton, UK, April 17, 2009: Bac2, the fuel cell materials and components company, announces an extended the family of products made from its ElectroPhen™ conductive polymer to include high temperature bipolar plates. High temperature operation, typically between 180 and 200 degrees Centigrade, is required to achieve good efficiency in polymer electrolyte membrane (PEM) fuel cells. The new plates are mechanically and electrically stable at over 200 degrees Centigrade. They will be on show for the first time at the Hannover Fair, Germany, from April 20-24.

Traditional bipolar plates for fuel cells have to be machined to create the channels through which fuel, air and water vapour flow. ElectroPhen is an electrically conductive thermoset material, made from readily available bulk constituents, which can be compression moulded and cured at room temperature. Bipolar plates based upon ElectoPhen do not need further machining, so they can be produced quickly and economically in any quantity. High temperature versions are subject to a proprietary conditioning process but this does not add significant cost or production time.

ElectroPhen is a unique, patented conductive polymer that requires relatively little loading with graphite to achieve the required conductivity for fuel cell plate applications. In addition to offering customised plates in high volume, Bac2 markets blank plates that customers can machine for prototyping work before committing to mould tooling expense.

Editors’ notes

Bac2 is the developer of ElectroPhen®, an electrically conductive plastic that is making a significant contribution to the early adoption of clean energy from fuel cell stacks. The company manufactures conductive plates for fuel cells using the material. Fuel cells are technically proven sources of clean energy for our planet, but adoption is presently limited by cost. Bac2 is in the process of developing ElectroPhen commercially and has patents pending in Europe, America and Asia. ElectroPhen is made from readily available low-cost constituents, can be pressed or moulded to complex shapes, and is robust enough for harsh environments. Customers in Europe, North and South America, and Asia use ElectroPhen plates in fuel cell development and manufacturing. In addition to its role in fuel cells, ElectroPhen has potential applications in many other electrical and electronic industries.
